"CAIS" Stage 2 Airtec intake kit specific for Ford Focus RS mk2. Practically the best intake currently on the market for the 2.5 Turbo 5 cylinder 20V, improved compared to the previous version by increasing the size of both the airbox and the integrated snorkel, channeling the air directly onto the "Group A" filter without receiving heat from the outside thanks to the carbon it is made of, with a glossy aesthetic finish and well-finished in detail. All this ensures an increase in power of about 10/20hp depending on the tuning of your car, with a clear improvement in performance noticeable right away! Completely Plug & Play without modifications, installable in a few minutes in place of the original intake.
